I will be picking my 2014 rt up from steve white in a couple days. I had the "maggie" 8lb supercharger with a diablo tune installed. It has the borla s-type exhaust and mopar cold air filter. Would like to hear from those with similar set up.

As long as the tune is correct, it should be smooth, reliable power all the way up... In my experience, if the tune is off in the slightest bit, you may notice some "light switch" effect.. granny driving or balls to the wall.

As for the IAT rise, there are things you can do after the fact to help lower them. Run Water Wetter and De-Ionized water in the intercooler
loop (not good if your car is exposed to freezing temps) Alternately you could add Water Wetter to the anti-freeze in the intercooler loop.
Upgrade the IC pump or add a larger fluid expansion tank. Some folks went the Killer Chiller route, it's involved and it's expensive but it
does seem to work quite well!

I'm sure you know of the guys at Steve White are Challenger fanatics. Especially Luke who is heading up my build. He should have some advice for me too. Thanks for the input. Oh ! I have a set of 275/40r20 Firestone Indy 500 tires going on a new set of 20x9 Yellow Jacket wheels to help me out. MY GOAL ?? Show the "PONY CARS" what MOPAR is all about !!!

If you aren't happy with the way it drives, you probably should start with getting it tuned on the dyno by the shop near them. My guess is you'd do it all thru SW since they did your install. Might get some extra ponies out of it too..

This is spot on. Power is delivered smoothly and reliably from factory FI setups. Every aftermarket FI install that I've driven has had the, "light switch" effect even if the tune is perfect. It's surprising at first but after you learn the car, things are less sketchy. Smiles appear shortly after.

I don't know if it is good or bad to see that others are experiencing the same problem I am having with my 8lb boost Maggie on my 2014 Challenger RT. It was recently installed and I can't enjoy the extra ponies. Mine is an automatic. In auto using the paddles it will get up to around 5000 rpm and seem to stumble before I can shift to second. The same if I start in 1st gear and get the rpm's up. The car will pull like crazy but I can't come close to pedal to the metal or even attempting a decent 0-60 run. Luke at Steve White is helping with my problem.

So, I don’t know because I’ve never had one, but i’ve heard of it. Is it possible to put keep the 6.1L hemi and put a supercharger/procharger in there and it still be able to withstand the amount of air and boost of HP? and if so how much? I’m just wondering. Also my transmission is the 727 so I...

I am looking to do the 6.2 cam swap into a 5.7. I know most say go aftermarket but that usually means VVT lock/limiter and a significant increase in cost. Not looking for maximum power but instead a budget swap as the NA 5.7 camshaft is not ideal for boost. Other than the cam, springs and...

Soooo as many of you all know I ran a nitrous based 5.7 for a couple of years now. If anyone does a search on my name you will find that I’ve product tested the MCLeod RXT clutch for the manual community( by this I mean I found out the hard way how terrible it is), I’ve done gear swaps, Cam...

I have a 2013 Challenger 392, it has a supercharger and high flow fuel injectors on it, perhaps that’s some of the issue. Or maybe it’s just me.
But I find it hard to drive around in 1st or second at lower rpms. It seems like the fuel pedal is “on or off. I don’t have issues starting off from a...

Hey guys, new to the forum (obviously) and in the market for a 2016-2017 ScatPak or Hellcat.
If I bought the Scat, a blower would end up on the car regardless. So, do I start with the Hellcat from jump street or go Scat Pak then add the blower?
Side note:
I ran my own performance shop for 16+...
